\"tAdHIhTG APPARATUS FOR RE CLAIMED RUBBER.

Patented Aug. 11, 1908.

T all whom it may concern:

' Be it known that I, WILLIAM A. KoNE-' MAN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Vvashing Apparatus for Reclaimed Rubber, of which the following is a specification.

In the art of reclaiming rubber from rubber-w'aste, involving-boiling of the material, in finely-divided condition, in an acid or an alkali solution, or in each solution in succession, the resultant product requires to be thoroughly washed in water to remove all remnant of the chemical adhering to it and cleanse itof the impurities known as muck contained in the made-upstock from which the articles forming the waste were produced.

My invention consists in a machine, the construction of which peculiarly adapts it for the washing-purpose referred to.

In the accompanying drawings, Figure 1 shows my improved washing-apparatus by a view in end-elevation; Fig. 2 is a transverse section of the same taken at the line 2 on Fig. 3 and viewed in the direction ofthe arrow, and Fig; 3 a longitudinal the line 3 on Fig. 1 and viewed inthe direc tion of the arrow.

In a suitable frame 4 provided with an in- '-clined. liquid-shedding table 5 from which a -screenlO and a b0x-like wash-water discharge-conduit 6 leads, as to settling-riflies, tanks or a sewer (notshown), 1s journaled above the shelf I to be of rectangular cross-section between a shaft 7, shown its journaled ends, though it may be of other shape. The shaft a'receptacle 8 for the material to be washed, this receptacle being hung in the frame to adapt it to' be turned, as and for the purpose hereinafter described, from its normal upright position, and consisting of a rounded bottom of perforated sheet-metal forming a upper portion 11, with closing heads 12, 12, through which the shaft passes. The screen is reinforced by bars ,or timbers 13 spaced apart and extending between the heads 12. Above the receptacle are supported spraying pipes 14 for supplying the washing-water tothe receptacle. On the shaft are secured to extend at i'ightangles to it and at uniform distances apart sets of wipers, each set consisting of two" wipers extending from the shaft in opposite'direc tion's, and thesets extending successively at right-pnglcs to. each other crosswisev of the section taken at passes lengthwise through outcof the shaft. Each wiper consists of arm 16 rigidly 15 secured on the outer end of the arm and in which is clamped a flexible rubber blade 18 to bear against the inner surface of the screen 10 in the rotation of the shaft. The dispose -tion of the wipers is such as to cause the blades 18 of the successive sets to overlap one another.

The shaft 7 is driven through the medium of a gear 19 on one end by a pinion 20 meshing therewith on a power-shaft 21. For turning the receptacle 8 it is rovided on each end, about the ends -of t e head 13,

with racks 22 engaged by pinions 23 on theother suitable inms to adapt it to be turned by ower.

1 0 operate the apparatus the rubber to be washed is dumped or run intothe receptacle, in quantity suflicient to partially fill it, the watcf is turned on to s ray from the pipes 14 into the receptacle, an the shaft 7 is rotated.

The particles of the recovered rubber undergoing washing are lifted by theblades of the Wipers in rotating the material, subjecting it to a stirring action to continuously present fresh portions of the batch to the spray. The mesh of the screen is much finer than the particles of rubber to prevent passage thereof through it while permitting the washing Water containing the impurities (mineral slimes, etc.) to run through it and sees. e b

way of the conduit 6. The flexible bladlls 18, by rubbing against the inner surface of the screen keep it clear to permit .the Wash-water to run freely through it, and they push the material ahead of them, squeezing it upon itself, thereby squeezing the chemical-muck particles of rubber and facilitating its remova by the action of the water. When the washing operation is completed the wateraft 7 arrested. To facilitate removal from spray is turned off and the rotation of the s t he washing-apparatus of the clean rubber, which has to be thoroughly dried preparatory to working it up into ture of rubber goods, adapted to be tipped to a horizontal position by turning the andle 27, whereb rotation of the shaft 24 ensues to engage t e pinions stock for the inanufac the receptacle 8 is 23 and turn the receptacleaccordingly on the shaft 7. The receptacle may, if desired, be: com letelyturned.overvand the washed ma.-

teria may be readily dumped oifj'slloyeled -material{tor be washed su ported on ftheinto suitable receptacles, conveyrs'," or'the' like,.for"removal to adrying apparatus, I

I also em lo {t'he apparatus for washing the finely divide material before subjecting itjto i the chemical solution treatment referred to: What I claim as new, and desire to secure by Letters Patent,is- 3' 1. In a rubber-washing apparatus, "the combination of a frame, a'receptacle for the frame and a screenottom, a rota tory'shaft extendingthrough the rece tacle,

wipers on ithe shaft having flexible lade- 5 ends extending againslif the inner surface of g frame and havin the screen, and a solution-receiving device below the screen, for thepurposeset forth.

2. In" a rubber-Washing apparatus, the

combination of a frame, areceptacle for the material to lie washed sup orted on ,the frame and comprising a roun' ed screen-bottom on a box-like upper portion with'-end-,

closing heads, a n'otatory shaft extending cured on the shaft to radiate therefrom and terminatin in heads having fastened upon them'fiexib e blades extending against the inner surface of the screen, and a sei'ution-receiving device below-the screen, for the purpose set forth.

4. In a'rubber-washing apparatus, the combination of a frame, 1a receptacle'for the material to. be Washed supported on theframe and comprising a rounded screen-bottom on a box like upper portion with endclosing heads, a Water-spraying pipe above said receptacle, a rotatory shaft extending through said heads, and wipers on the shaft, having flexible blade-ends extending against the inner surface of the screen, for the purpose set fQrthf =5. In a rubber-washing apparatus, the combination of a frame, a reeeptaelefor the material to be washed rotatably supported on the frame and having a screen-bottom, a
